Since the 1970s, the Xikrin people and their relatives have faced large infrastructure projects in the Middle Xingu, such as the Trans-Amazonian Highway (BR-230) and the Kararaô Project, which became the Belo Monte hydroelectric dam. The Association itself was founded in 2018 to defend the Xikrin people from the impacts of these projects.
The Xikrin say that “the Xingu River holds the Bacajá River”: when the Xingu rises, the Bacajá is full; when it falls, the Bacajá drops with it. In the reduced-flow stretch of the Xingu, floods fell from 80 to 9 days a year, and extreme droughts rose from 45 to 104 days (Revista Pesquisa FAPESP).
Because of these impacts, the communities are served by compensation and mitigation measures under the Belo Monte Basic Environmental Plan (PBA), the responsibility of the company Norte Energia, in culture, territorial management, community organization, education, health and productive activities. Berê has seven years of experience in this field and works to lead the decisions: actions that require traditional knowledge are carried out with the PBA-CI (Indigenous Component) executing company, with the Association as co-executor and proponent.
